T 0 aZZ 10/ 10772 it may concern:

Be it known that I, HARRY lV. RUBY, a citizen of the United States,residing at Springfield, in the county of Clark and State of Ohio, haveinvented certain new and useful Improvements in Cut-Outs, of which thefollowing-is a specification, reference being had therein to theaccompanying drawing.

This invention relates to a cut-out for the exhaust of an internalcombustion engine and is designed more particularly for use withautomobiles and the like.

The object of the invention is to provide a cut-out of this kind whichwill be very simple in its construction and easily operated.

A "further object or" the invention is to provide such a device in whichit will not be necessary to use springs to control the valve, as thesprings are-seriously aflected by the heat from the exhaust; and to thisend it is a further object of the invention to provide such a devicewith a gravity valve.

A further object of the invention is to so mount the valve that when itis moved to its open position it will'not only open the supplementaloutlet but will be moved to such a position that it will partiallyobstruct the flow of the exhaust gases to the normal outlet and thusdivert the same through the supplemental outlet.

A further object of the invention is to provide means for securing thevalve in its closed position so that it will not rattle or chatter.

A further object of the invention is to provide such a device in whichthe valve and its seat will be readily accessible for cleaning, or otherpurposes.

Further objects of the invention will appear as the device is describedin detail.

In the accompanying drawings Fig. 1 is a sectional view talrenlongitudinally of a cut-out embodying my invention; Fig. 2 is an endelevation of such a cutout; and 3 is a side elevation of a modified formof the cut-out.

In these drawings 1 have illustrated one embodiment of my invention,with a slight modification thereof. In both forms illustrated the devicecomprises a tubular body adapted to be connected in the exhaust line ofan internal combustion engine and having a supplemental outlet which isclosed by a gra ty a as s, a raven-ah i l be seated either by its ownweight or by auxiliary weights connected therewith. This valve isarranged within the body of the cut-out and is supported in such amanner that when moved to its open position it will be positioned in thenormal path of the exhaust gases near the normal outlet of the body. andwill thus divert the gases through thesupplemental outlet, or cut-outopening. In both forms the valve is provided with a stem which extendsthrough the supplemental opening and is mounted exteriorly of the body.Preferably this stem is in'the form of a lever which is pivotallymounted and which may be acted upon by suitable operating device to movethe valve into its open position. In one form of the device it isprovided with a gravity lock to secure the valve in its closed position,the operating device being of such a character that it will first movethe lock to its inoperative position and then open the valve. It will beunderstood, however, that the particular forms of the cut-out here shownhave been chosen for the purpose of illustration only and that thedevice may take various forms without departing from the spirit of theinvention.

In both embodiments of the invention here illustrated the cut-outcomprises atubular body 1 adapted to be connected in the exhaust-line.It is preferably, but not necessarily, in the form of an attachment tobe applied to the exhaust pipe after the latter has been installed, and,as here shown, it is capable of being applied to the exhaust line at anytime. To this end the body is substantially cylindrical in shape and isopen at both ends to permit the pipe to be inserted therein, as shown at2. The body may be conveniently applied to the exhaust pipe by clampingand I have here shown the body as divided longitudinally into two parts,which parts are provided with cooperating apertured lugs 3 to receivebolts 4: which serve to connect the two [parts of the body one to theother and to clamp the same onto the exhaust pipe. which has an openingtherein. The body is provided with a 'supplement'ahor cut-out, openingwhich is preferably formed in the bottom wall thereof in line with anopening in the exha'ust pipe, and, as here shown, is surrounded byedownwardly converging flange 5 which forms a valve seat to receive thevalve 5- he Yell? 5; its has i l tatedis preferably a gravity valve and,as here shown, is arranged within the body and adapted to engage theconverging flange forming the valve seat and thus close thesupplemental, or output, outlet. The weight necessary to hold the valvefirmly on its seat may be imparted thereto either by forming the valveitself of a sufiic-iently heavy construction or'by the use of auxiliaryweights. he valve preferably comprises a rounded head portion which willengage the valve seat with a relatively narrow surface of contact andwhich will lie within the recess formed by the depending flanges andwill thus be positioned out of the path of the exhaust gases as theypass through the exhaust line normally, so that the valve will offer noobstruction to the normal movement of the exhaust gases. The valve hasconnected therewith a stem 7 which extends through the outlet openingand is movably mounted exteriorly of the body of the cutout in such amanner that the valve can be moved into and out of engagement with itsvalve seat. Further, the manner of mounting the valve stem is such thatwhen the valve is moved out of engagement with its valve seat it will bemoved into a position adjacent to the normal outlet of the body of thecutout and will thus he in the path of the exhaust gases and will tendto divert the same through the supplemental outlet, the valve shown inFigs. 1 and 2 having the stem 7 flattened and widened adjacent thereto,as shown at 7, to further obstruct the flow of the gases. Preferably thevalve stem is pivotally mounted and, as shown in Figs.

1 and 2, it is in the form of an arm, or lever, which extends downwardlyfor some distance below the supplemental outlet, and then extendsupwardly and rearwardly, that is, in the direction of the normal flow ofthe exhaust gases. This lever, or valve stem, is pivotally mounted nearits rear end on brackets 8 carried by the body, the end of the leverpreferably extending between the two brackets and being mounted upon apin 9 which extends through the brackets. The

shape of the lever and the location of its axis are such that when thelever is rocked about its axis the valve will be moved into the positionshown in dotted lines in Fig. 1. The valve may be operated in anysuitable manner but I prefer to operate it by means of a cable extendingtherefrom to the point from which the cut-out is to be controlled, suchas the instrument board of an automobile.

. Some means must be provided to prevent the valve from rattling orchattering due to the vibration of the machine or to the action of theexhaust on the valve. This may, in some cases, be accomplished byproviding the valve with sufficient weight to hold it firmly on its seatunder all operative conditions, but in other cases this is not desirableand I have, therefore, shown in Figs. 1 and 2 a locking device forpositively securing the valve in its closed position. This lockingdevice may take various forms but is preferably of such a character thatit will move by gravity into its locking position and is so connectedwith the operating device for the valve that the locking device will befirst moved into an inoperative position and the valve then moved intoits open position. The locking device may take various forms but asshown in Figs; 1 and 2 it comprises a locking member, or arm, 10, whichis pivotally mounted on the body, or main casing, of the cut--out,preferably on the arms 8 between the axis of the valve stem and the bodyof the cut-out. The out er, or'free, end of the locking arm isbifurcated and the bifurcated portions 11 thereof extend on oppositesides of the valve stem 7. These bifurcated portions of the arm arepreferably curved outwardly and spaced apart such a distance that whenthe locking arm is moved into a position adjacent to the cut-out openingthe two parts of the arm will lie on opposite sides of that opening andwill not interfere with the passage of the exhaust gases therethrough.The outer, or bifurcated, portion of the looking arm is of such weightas to insure the movement of the locking device by gravity into itslocking position. The lockingarm has a part adapted to engage the valvestem 7 when the locking device is inits operative, or locking, position,and, as here shown,'this part comprises the end of the body portion ofthe arm, which liesbetween the bifurcated portions 11 thereof, as shownat 12, and the valve stem is provided with a portion, such as a lug, orshoulder, 13 with which the part 12 of the locking arm enlib":

gages when the valve is seated and the looking arm is in its operativeposition. locking arm also has a part to engage the valve stem andimpart upward movement thereto after the locking arm has been moved farenough to clear the part 13 of the valve stem. As here shown, this partcomprises a cross bar 14 extending between the two bifurcated portions11 of the looking arm and spaced below the valve stem such a distancethat itwill not engage the latter until the locking arm has been movedto an inoperative position. The operating device for the cut-out ispreferably connected with the locking device and, as here 1 shown,comprises a cable 15 connected with cross bar 14 wil then pick up thevalve stem and. m ve the valv n o its open posi- The V tion, as shown indotted lines inFig. 1. When the operating device is released the valveand-locking arm will move downward by gravity and the weight of.thelocking device willassist in moving the valve firmly into atightlyclosed position and whent-he valve has been moved into a tightly closedposition the part 12 of the locking arm will engage the part 13 of thevalve stem to positively hold the valve in its closed position.

In Fig. 3 the general construction of the cut out is the same as thatshown in Figs. 1 and '2 but the valve stem, or lever, which is shown-at16, is somewhat differently arranged. hereshown, the valve stem extendsdownwardly from the valve and is then curved rearwardly and upwardly andis pivotally mounted on the body, at 17 and is. provided with anupwardlyextendingarm 18 which may be connected with any suitableoperating device. The shape of this lever and the arrangement of itsaxis are such that when the valve is opened it will be moved upwardlyand rearwardly so that it will lie adjacent to the normal outlet openingof the body and thus tend to divert the exhaust gases toward thesupplemental outlet. In this form of the device no locking device isprovided but the valve, which is shown at 19, is of such a sizeandweight that it will be held firmly in its closed position by gravity,

The operation of the cut-out will be readily understood from theforegoing description and it will be apparent that I have provided acut-out which is very simple and inexpensive in its construction, whichcan be very easily operated, and which is so constructed and arrangedthat both the valve and its seat are readily accessible for cleaning orotherpurposes Further, by the use of a gravity valve I eliminate the useof springs, which are objectionable in a device of this kind for variousreasons, one reason being that the temper is drawn from the springs bythe heat of the exhaust and they quickly lose their effectiveness.Further, the springs must be of considerable stiffness and render thevalve more or less diflicult to operate. This construction also enablesthe operating" device to be placed upon the dash instead f even h o b ad an Wh nan operat n ab is u ed t i c b d no need o e main i ed t a i nees ar ith an e diea y pring op ra ed e trcut Further, the valv h s a reativ y, n rro see at c nt ct on its. va e seat an wil seat teel ina vdepos t hich may la up nihej al sea nd there beli tle no ten e y to leage on the part i he valve, andfu h n he e Will, be li tle or e tendencyo th al to stick in its seat. P lVIoreover, I have provided the u W th alock which will pbsiti ly hold the valve in its closed position andprevent the same from rattling or chattering under any condition ofservice. The whole device is of such a character that it can be quicklyand easily applied to an exhaust pipe ing which registers with th outletopening of the cut-out. This results in a much stronger construction andone in which the parts are much less liable to loosen and rattle. Itwill also be noted that the valve is mounted on the body of the cut-outexteriorly thereof so that there are no pivot pins, or other parts,extending through the wall of the exhaust line to loosen and leak.

IVhile I have shown one embodiment of my invention, and a minormodification thereof, I wish it to be understood that I do not desire tobe limited to the details shown and described, as various modificationsmay occur to a person skilled in the art.
